Description

Chemical reaction pipeline explosion emergency protection device and protection method thereof Technical Field The invention relates to the technical field of explosion protection of chemical reaction pipelines, in particular to an emergency protection device for explosion of a chemical reaction pipeline and a protection method thereof. Background Chemical reaction is an important link of chemical production, and specifically, materials for producing chemical products are reacted in a reaction kettle and other containers through chemical reaction. In the chemical reaction process, liquid materials such as reaction materials, solvents and the like are pumped into a kettle through a conveying pipeline arranged in a workshop. The safety of the delivery conduit for pumping the material is therefore critical to improving the safety of the production. Specifically, in the process of production, the pumped organic solvent and the like are inflammable and explosive materials, and the characteristics of low flash point, strong explosiveness and the like are often presented, and in the process of pumping, once sparks occur in a pipeline (the sparks are formed due to static electricity on the pipeline in the actual production process), the conveyed organic solvent in the pipeline immediately explodes. Because the pipelines are processed by adopting metal materials, the broken pieces of the pipelines are splashed due to the exploded pipelines, the high kinetic energy broken pieces of the splashed pipeline are extremely easy to cause the broken of other pipelines, the solvent with certain hydraulic pressure is easy to gush, the organic solvent is ignited due to the explosion of the pipeline, and the broken pipelines after the normal pipelines, especially the impact, are easy to ignite, so that the interlocking explosion effect is caused. Based on the above, in order to improve the safety of a chemical pipeline pumping solvent, the Chinese patent publication No. CN217273581U discloses a chemical pipeline explosion-proof safety system, which mainly comprises a pressure gauge and a block valve, wherein the pressure gauge is used for detecting the pressure of a pipeline, the pressure gauge is arranged on the pipeline and is connected with a controller through signals, the controller is connected with the block valve through signals, a detection device is further arranged on the pipeline, the detection device comprises a detection mechanism and a prompt mechanism, the detection mechanism is arranged on the pipeline, the prompt mechanism is arranged on a vibration-proof bracket, the detection mechanism drives the prompt mechanism through a connecting rod, and an air bag is inflated through an inflation assembly in the prompt mechanism to give out leakage warning. However, the technical solutions disclosed in the above patents in the prior art are all processed in an early warning manner, namely, when the pressure of the pipeline is abnormal, the pipeline is processed through an alarm system. In the actual production process, the emergency state cannot be timely processed by adopting early warning treatment, such as pipeline explosion, most of the pipeline explosion is short in explosion time, the explosion point position cannot be accurately predicted, the sporadic performance is high, the timeliness is high, and once the explosion causes a chain reaction, serious production accidents are necessarily caused.
